[BackgroundStore] activeBackgroundUrl: No entry or URL found

Error message

[BackgroundStore] activeBackgroundUrl: No entry or URL found for ID "${lookupId}"

What it means

Warn from the background store's activeBackgroundUrl computed. The active card references a background through extensions.airi.modules.activeBackgroundId (normalized from the 'image-journal-' prefix to the storage prefix), but entries has no record with that ID, so the computed returns null and the scene renders without its background. The entry-existence gate also exists so backgrounds deleted in other windows stop rendering via stale cached blob URLs.

Solutions

1. If this fires once at startup, ignore it - hydration finishes asynchronously and the computed re-evaluates
2. If persistent, reset the stale reference: set extensions.airi.modules.activeBackgroundId to 'none' or to an ID present in getCharacterBackgrounds
3. Re-create the missing background (re-upload or re-journal the image) so entries.value.has(lookupId) becomes true
4. Check the BroadcastChannel 'airi:background-sync' flow when multiple windows are open - deletion in another window is intentionally honored here

Example fix

// before
const bgUrl = backgroundStore.activeBackgroundUrl.value

// after: tolerate the hydration window and the deleted case
const bgUrl = computed(() =>
  backgroundStore.loading.value ? null : backgroundStore.activeBackgroundUrl.value,
)
watch(bgUrl, (url) => {
  if (!url) resetToDefaultScene()
})

if (!backgroundStore.loading.value) {
  const url = backgroundStore.activeBackgroundUrl.value
  if (!url) resetToDefaultScene()
}

function hasBackgroundEntry(
  entries: ReadonlyMap<string, unknown>,
  id: string | undefined | null,
): id is string {
  return typeof id === 'string' && id !== 'none' && entries.has(id)
}

When it happens

Trigger: activeBackgroundId points at a deleted journal/selfie background; the store's async initializeStore() has not hydrated entries yet (first render after boot); a cross-window deletion broadcast has not been applied in this window; or profile/card JSON was synced to a machine where the background blobs were never created.

Common situations: User deleted a journal image that was set as the active background; duplicated profiles across devices sharing card data but not IndexedDB blobs; races between app startup and the auto-init store; leftover IDs after the image-journal prefix migration.
